Manly appeared to be controlling both sides of the ruck in an opening stanza despite three tries being disallowed following obstruction rulings, the Sea Eagles being denied in the 7th and 25th minutes and the Cowboys being denied in in the 21st minute. Manly dominated possession before being rewarded a penalty goal in the 13th minute.
With in-form Manly hooker Michael Monaghan sideline with concussion, Sea Eagles fullback Brett Stewart finally crossed after selling a dummy and diving over in the 30th minute.
The Cowboys struck back on the stroke of half time through forward Jacob Lillyman to post a 6-all score line and put the North Queenslanders back in the hunt.
The second half saw the return of Monaghan who had an immediate impact before back rower Anthony Watmough scored folowing a tap penalty from 10 metres out.
Manly centre Steve Bell was next to score in the 53rd minute before half back Matt Orford slotted a penalty goal in the 60th minute to give the Sea Eagles an 18-6 lead.
The match was put out of the Cowboys reach six minutes later after Monaghan and Watmough combined to see centre Jamie Lyon over the line.
With the match won and lost, lock forward Luke Williamson scored in 75th minute to put the icing on a comprehensive second half display for the Sea Eagles.
